(del theta a)/(b+ce^(x))

int(a)/(b+ce^(x))dx=

int(a)/(b+c.e^(x))dx=

Evaluate: int(a)/(b+ce^(x))dx

If x = r cos theta, y = r sin theta, Find (del (x, y)) / (del (r, theta)), (del (r, theta)) / (del (x, y))

If x = r cos theta, y = r sin theta then prove that (del (x, y)) / (del (r, theta)) xx (del (r, theta)) / (del (x, y)) = 1

If u =x ^(2) + y ^(2) evaluate (del^(2)f)/(del x ^(2)) + (del ^(2) f)/(dy ^(2)):

Find (del f)/(del x), (del f)/(del y),(del^(2) f)/(delx^(2)), (del^(2) f)/(del y^(2)) , at x=2, y=3 if f(x,y) =2x^(2) + 3y^(2) - 8xy .

If u=log sqrt(x^(2) + y^(2)) , then (del^(2) u)/(del x^(2)) + (del^(2)u)/(del y^(2)) is
